MOTOR SUSPENSION.

SPECIFICATION forming part of Letters Patent No. 761,540, dated May 311904.

Application filed November 19, 1903. Serial No. 181,882. (No model.)

To all whom, it may concern:

Be it known that I, WILLIAM G. PRICE, a

citizen of the United States, residing at Kingston, in the county ofUlster and State of New York, have invented certain new and usefulImprovements in Motor Suspensions; and I do hereby declare the followingto be a full,

clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention relates to improvements in car-trucks, and has particularreference to motor-supporting means therefor. r

The object of the invention is the provision of a motor-support whichshall prevent the transmission of vibration from the motor to thecar-body carried by atr'uck, and this object is attained by theprovisionof means in combination witha truck for supporting a motor independentlyof the same.

In carrying out this invention I contemplate providing, in combinationwith a car-truck and equalizer-bars therefor, motor-supporting meanscarried by said bars.

The invention consists in certain novel constructions, combinations, andarrangements of parts, as will be hereinafter fully described andclaimed. a

In the accompanying drawings, Figure 1 represents a top plan View of acar-truck provided with an embodiment of the present improvedmotor-support. .Fig. 2 represents a Vl6W\ in side elevation of the same.Fig. 3 represents an enlarged detail fragmentary transverse verticalsection taken on the plane of line 3 3 of Fig. 2. Fig. 41 represents atransverse vertical section taken on the plane of line 4: 4 of Fig. 1and looking in the direction indicated by the arrow. 7

In the present art it is 'well known that serious objections to thecommon form of mounting of motors arises from the fact that vibrationsfrom the gear are felt within the car supported upon a truck carrying a'given motor. The motors are usually carried beffore conceived of themounting of the motor practically independently of the truck, wherebythe vibration. will not only fail to affect the car, but will not to anymaterial degree affect the car-truck, and this arrangement in itspreferred embodiment is delineated in the accompanying drawings, inwhich 1 1 indicate the side frames of a truck, connected at their endsby end frames 2 2. r The side frames 1 are connected by suitabletransoms 3 3,'spaced apart and supporting therebetween acar-bodycarrying .bolster 1, mounted upon springs 5 5, carried by saidtransoms. Each side frame 1 is bent into yoke shape and formed with apedestal at each end extending just outside of and contacting with theside wall of its respective box 6 6, inclosing the end of thecorresponding axle 7, said axle carrying sup porting-wheels 8 8. Eachbearingbox 6 is provided with laterally-projecting flanges 9 9,inclosing the respective pedestal and limiting the given side frame.against lateral play. Each side frame 1 is supported upon cushions orsprings 10 10, positioned beneath a given. side frame and resting uponan equalizer-bar 11, said barextending between and connect-' ing the twoboxes 6 atone side of the truck, said bar preferably consisting of aplurality of beams spaced apart, as best seen in Fig.3, and securedtogether and to the boxes 6 by bolts 12 12, extending through said beamsand through lugs 13 13, projecting laterally from the boxes. Each bar 11is spaced below its corresponding frame land is bent about the boxes 6at its ends, with the end portions of Each of the equalizer-barsllcarries at each end brackets 28 28, bolted thereto and extending aboveand inclined inwardly therefrom.

I Each setof said brackets 28 is at its upper end bent into a hook 29,between the members of which is pivotally secured a link 30. The lowerend of each link 30 pix'otally engages the web of a brake-shoe 31 forsupporting the samein position for engaging one of the wheels 8.Suitable links 32 32 connect with the web of each of said shoes 31 andat their outer ends engage an operating-lever 33, the levers at one sideof the frame being connected together by a turnbuckle 34. A bracket 35depends from each equalizer-bar near each end of the respectiveturnbuckle 34 and extends beneath the same for supporting saidturnbuckle in case of accidental displacement of the parts and droppingof said turnbuckle. One of the levers 33 at each side of the truck ispreferably left with its upper end free to contact with one of thetransoms 3, while the other lever is engaged by a draw-rod 36, saiddrawrod being connected to any suitable. draft mechanism.

I have above briefly outlined the general construction of. the presentimproved truck and mentioned elements which are fully covered in thespecification and claims of other applications filed by me and which donot constitute the subject-matter for claim in the present application.

The subject-matter for claim in the present application is themotor-supporting means, which I shall now proceed to describe, thepreceding description being given in order that the claimed structureshall be clearly understood by those skilled in the art.

Between the beams comprising each equalizer-bar 11 is arranged a bracket15, said bracket being secured by suitable bolts 16 16 and beingprovided with aflattened apertured portion 17. A verticallongitudinally-movable bolt 18 extends through the aperture of saidflattened portion of the bracket and is surrounded beneath said bracketby a comparatively small spring or other suitable cushion ing 20,carried by said bolt and supported by a nut 21, threaded onto the same.Above the flattened portion of the bracket is arranged a relativelylarge spring or other cushion 22, surrounding bolt 18 and supported uponacap 23, resting upon the respective bar 11. The upper end of the springor cushion 22 supports a cap 24, which in turn carries the end of a bar25, said end of the bar being apertured and the bolt 18 being passedthere-v through and retained in position by asuitable nut 26. The bar 25extends across the entire truck with its flat faces lying in verticalplanes; but the ends of said bar are preferably twisted, as indicated inthe drawings, so as to lie flat upon the caps 24.

' In operation a motor 27 is suspended from the bar 25 and geared to oneof the axles 7 for driving the same in the usual manner. Aplurality ofmotors may be supported in a similar manner, and it will be seen thatvibrations of the motor will be absorbed by the cushions 19 and 22, andwhatever vibration might not be taken up thereby will tend simply toall'ect the bars 11 and the axles of the car-supporting wheels. It willbe seen that the motor may be supported practically independently of theear-truck frame and the object sought thus effectually attained.

Among the many advantages obtained by the present improved structure maybe mentioned the fact that the supporting of the brake-rigging, as wellas the motor, directly from the equalizer-bars and independently of thetruck-frame makes possible the removal of the truck-frameindependentlyof such brakerigging and motor, and thereby enables accessto be had to the motor withoutdisturbing the motor, wheels and axles,and brake rigging for permitting cleaning and repairing of the parts.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

1. In a mechanism of the class described, the combination with a car-truck and a divided equalizer-bar, of a springinterposed between theparts of said bar, means connecting said spring to said bar, andmotor-supporting means connected with said spring.

2. In a mechanism of the class described, the combination with acar-truck and axles therefor, of divided equalizer-bars connecting saidaxles, a bracket arranged between the parts of each of said bars, a boltextending through each of said brackets, a spring arranged above thehorizontal plane of the lower edge of each of said brackets between theparts thereof engaging said bolt at one end and engaging said bracket atthe other, a spring mounted upon each of said bars above the respectivebracket surrounding its corresponding bolt, and motor-supporting meansengaged by said bolts and supported by said last-mentioned springs.

3. In a mechanism of the class described, the

combination with a truck and a divided equalizer-bar therefor, of acushion interposed between the parts of said bar and carried by the bar,and motor-supporting means connected with said cushion.

4. In a mechanism of the class described, the combination with acar-truck and a divided eq ualizer-bar therefor, of a cushion interposedbetween the parts of said bar, a motor-support carried by saidequalizer-bar, and connections between said motor-support and cushion.

5. In a mechanism of the class described, the

, combination with a car-truck and a'divided equalizer-bar therefor, ofa cushion resting upon said bars, a motor-support resting upon saidcushion, a cushion between the parts of said bar, and connectionsbetween said motorsupport and said last-mentioned cushion.

relatively small and located entirely between the parts of the saiddivided equalizer-bar and the other of said springs being relativelylarge and disposed entirely above said equalizer-bar. 9. In a'mechanismof the class described, the

combination with a car-truck and a divided equalizer-bar therefor, of abracket carried between the parts of said bar and extending upwardlytherebetween, a spring arranged within said bracket above the lower edgeof said bar, and motor-carrying means engaging said spring.

In testimony whereof I hereunto'aflix my signature in presence of twoWitnesses.
